   "StackState" isn't actually part of Rev/MC. Instead, it's a variable I'm 
using as a flag, and every handler you've got should set this flag to 
whatever value is appropriate. Let the first line in every handler be "put 
'YadaYada' into StackState", and use "put 'idle' into StackState" as the the 
last line of each handler.

   As far as i know, what StackState does isn't actually built into Rev/MC -- 
so you have to do it 'by hand', as it were.

   Strictly speaking, things *can* work with a repeat loop -- it's just that 
you don't *want* things to work with a repeat loop. Bad side effects, man.
